MAX30102 Heart Rate & SpO₂ Sensor Module

The MAX30102 Heart Rate & SpO₂ Sensor Module is an integrated optical sensing module designed for detecting heart-rate and blood-oxygen-related signals using red and infrared LEDs together with a photodetector. It communicates with a microcontroller through an I²C-compatible interface. It is suitable for Arduino, ESP32, ESP8266, Raspberry Pi and other embedded projects, including wearable prototypes, fitness projects, biometric experiments and IoT applications. Important: This is an educational/prototyping sensor module, not a medical device. Its readings should not be used for medical diagnosis or treatment.
